"Looks like you're listening on another device" error
Okay so, I recently gave my sister my iTunes account details to allow her use it on her phone. The problem is, whenever I want to listen to my music, I think sometimes she's listening to hers and I get the error mentioned in the summary. I saw another post that said I needed to set up a family plan. I have done that and I still get the same error.
Please, what else can I do?
